To all whom it may concern:

Be it 'known' that I, FRED C. Danni, a

' citizen of the United States of America,

and residentof Chicago, county of Cool: and Stateof Illinois,haveinvent'ed certain;

new and useful Improvements in Drives for Linotype-Machines, of whichthe following is a specification.

My inventionrelates to motor drives for linotypes and has for its objectimprovements in such devices.

Linotype machlnes have been operated for some time by gear connectionsfrom an electric motor, but owing to the high speed of the motors thegears wear rapidly and soon become noisy unless there'i's some meansfor" adiusting such ears to each othen- The adjustment whic I havedevised for over coming this diiliculty is designed to be apw plied tothe existing machines Without a'lt'er 1 ation, and is adapted tosmallvariations of adjustment.

In the accompanying drawings Figure 1 is an elevation showing a portionof .the frame and pedestal of a linotype; and Fig.

2 is a longitudinal section of one end of the drive shaft and partssupported thereontv In the said drawings, F is a portion of the frame,and P a portion of the pedestal of a lii'iotype machine. I Att'he backof the machine is a drive shaft 1), on which is a clutch pulley Ahavi'nga hub B. A rodC scrvesto connect the pulley to the shaft D, and on thehub B is a large gear G.

Supported in the frame F below the drive shaft 1), and sligl'itly to therear, a shaft H which belongs to the machine andope'rates part of themechanism thereof. G n the projecting end of the shaft 5 I pivotamo torcarrying platform E in a substantially horizontal position beneath thegear G.

In linotype machines as constructed, the

7 frame F is secured to-thc pedestal P by bolts tutc therci'or'a rod Jhaving a collar K and a nut L serving the same purpose as the originalbolt. Below the collar K, the rod J projects through a. hole in the freeend of the platform E, and is provided with nuts N for adjusting theplatform on its pivot Sr Specification at Letters Patent.

I remove one of these bolts and'substi- The motorM is mounted upon thisplatform l and is provided with a pinion T for engaging the gear G.

It will be observed by the construction shown that-byslacking the uppernut N and adjusting the lower one,-the platform will he turned on itspivot S to move the pinion T nearer to or farther from the gear KG;

Also, that the screw adjustment involved may bemade while the motoris inoperation so that the area of the adjustment may be determined by thesound of the gears justment is obtained the upper. nut N may be screweddown on the rod J and thus become-a lock nut-to hold the adjustment.

What I claim'is:

1. The combination with the drive shaft and frame of a linotype machine,of a gear mounted upon the drive shaft, a platform pivoted upon? theframe, a motor secured to you platform, a pinion driven by the motor,

and ascrew adjustment for turning the platform on its pivot'so as'toadjust the pinion with respect to the gear.
